Completion of Charge
Charge completion is indicated by the CHARGED (green) LED. When lit, the charger
has switched to the Maintain Mode of operation. If the 12V DEEP CYCLE battery type
was selected, the CHARGED (green) LED comes on when the battery is charged
enough for normal use.
Maintain Mode (Float-Mode Monitoring)
When the CHARGED (green) LED is lit, the charger has started Maintain Mode. In this
mode, the charger keeps the battery fully charged by delivering a small current when
necessary. The voltage is maintained at a level determined by the BATTERY
TYPE selected.
NOTE: The maintain mode technology utilized in DieHard chargers allows you to safely
charge and maintain a healthy battery for extended periods of time. However, problems
with the battery, electrical problems in the vehicle, improper connections or other
unanticipated conditions could cause excessive voltage draws. As such, occasionally
monitoring your battery and the charging process is recommended.

the vehicle could cause damage to the vehicle’s electrical system. NOTE: If you have
charged the battery and it still will not start your car, do not use the engine start feature,
or it could damage the vehicle’s electrical system.

Engine Starting Notes
During the starting sequence listed above, the charger is set to one of the following
three states:
Wait for cranking – The charger waits until the engine is actually being cranked before
delivering the 80 amps for engine start. The charger delivers charge at a rate of up to 12
amps while waiting. While waiting for cranking, the digital display will show rdy.
Cranking – When cranking is detected, the charger will automatically deliver up to its
maximum output as required by the starting system for up to 3 seconds or until the
engine cranking stops. The digital display shows a countdown of the remaining crank
time in seconds. It starts at 3 and counts down to 0.
